If the battery temperature exceeds 60°C, check the battery for electrolyte overflow. If electrolyte overflows, handle the leakage immediately.

Electrolyte Leakage

In the case of electrolyte leakage, counteract and absorb the leaking electrolyte immediately.

When moving or handling a battery whose electrolyte leaks, note that the leaking electrolyte may harm human bodies. If the electrolyte leaks, use the following substances to counteract and absorb the leaking electrolyte:



Sodium bicarbonate (baking soda): NaHCO3



Sodium carbonate (soda): Na2CO3

When using substances to counteract and absorb electrolytes, strictly follow the guidelines provided by the battery manufacturer.

If any personnel are exposed to battery electrolyte, wash the exposed area with clean water immediately and seek medical advice if the situation is serious.

1.6 Laying Out Cables

Binding Signal Cables

UPS5000-A-30 kVA & 40 kVA & 80 kVA User Manual

1 Safety Precautions

Issue 11 (2018-12-10)

Signal cables must be bound separately from strong-current cables and high-voltage cables.

Laying Out Cables

When the temperature is low, a violent strike or vibrations may damage the cable sheathing. To ensure cable safety, comply with the following requirements:



Cables can be laid, or installed, only when the temperature is higher than 0°C (32°F). Handle cables with caution, especially at lower temperatures.



Before laying out cables that have been stored in temperatures lower than 0°C (32°F), move the cables to an environment that is at the requisite ambient temperature. Store them in this environment for at least 24 hours.



Do not drop the cables directly from the vehicle.



As the insulation layer of a cable may age, or be damaged from high temperatures, ensure a sufficient distance between cables and the DC busbars, shunts, and fuses. Cables prepared by the customer should be flame resistant. Cables must not be routed behind the air exhaust vent of the cabinet. The air exhaust vent should not be blocked by any object.

Before connecting a cable, ensure that the cable and cable label to be used meet the actual installation requirements.

1.7 Information About Foreign Objects near UPS Equipment Installation

The purpose of this note is to provide information and warnings about the potential risks of the operational integrity of an installed UPS. These risks are caused by foreign objects in or near the UPS modules and relevant auxiliary equipment/components.

These risks are particularly high if conductive materials have entered the UPS modules/units or the channels in the relevant auxiliary equipment/components.

Potential risks include damage to installed UPS equipment and subsequent power derating and power failure of loads at critical positions.

Huawei UPS uses the highest safety standard in equipment design to ensure that live parts are not in contact with the exterior and that no foreign object will enter the equipment during operation.

However, when the UPS baffle plate and cover are open and the electrical wiring terminals are exposed by the electrical contractor/installation personnel who are setting up a power line connection, it is almost impossible to ensure that no foreign object will enter Huawei UPS during onsite installation.

It is common to have someone working in the same room as the UPS during onsite installation. Sometimes some people may be working above the UPS and relevant auxiliary equipment/components.

To avoid serious damage to the onsite operation, property hazards, and personal injury including fatal injury, it is the responsibility of each equipment manager or construction

2.2.2 Working Modes

2.2.2.1 Normal Mode

When the UPS works in normal mode, the rectifier converts the AC input voltage into the DC voltage, which is then raised to the bus voltage by the power factor correction (PFC) circuit. Then one part of the voltage passes through the DC-DC circuit to charge the battery string, and the other part is converted by the inverter into AC voltage outputs. The two conversions ensure high-precision and high-quality output voltages, protecting loads from interferences such as input harmonics, burrs, and voltage transients. Figure 2-3 shows the conceptual diagram of the UPS working in normal mode.

2.2.2.2 Bypass Mode

If the inverter does not start or is manually shut down after the UPS is powered on, the bypass supplies power to loads. The UPS automatically transfers from normal mode to bypass mode if it detects power unit overtemperature, overload, or other faults that may cause the inverter to shut down. The bypass power supply is not protected by the UPS which means it may be affected by mains outage, and incorrect AC voltage or frequency. Figure 2-4 shows a conceptual diagram of the UPS working in bypass mode.

Figure 2-4 UPS conceptual diagram in bypass mode

2.2.2.3 Battery Mode

If the AC input voltage is not normal, the UPS transfers to battery mode to obtain power from batteries. The inverter then converts the power into AC outputs. Figure 2-5 shows a conceptual diagram of the UPS working in battery mode.

2.2.2.4 Maintenance Bypass Mode

The current flows through the maintenance bypass, instead of the power unit or bypass unit. UPS maintenance can be performed in this mode.

Figure 2-6 UPS conceptual diagram in maintenance bypass mode

2.2.2.5 ECO Mode

The economy control operation (ECO) mode is an energy-saving mode, which you can configure on the liquid crystal display (LCD) or web user interface (WebUI). In ECO mode, when the bypass input voltage is within the ECO voltage range, the bypass combined switch turns on, and the bypass supplies power. When the bypass input voltage is beyond the ECO
